I've had this HPE-500y since May 2011 and for the last two months at least it unexpectedly would restart once or twice a day. Sometimes it would happen in the middle of me browsing and sometimes it would just happen when I'm not around. The only new hardware I've added is a second internal harddrive and a firewire card, both of which had already been in there months prior to this problem. When I go to event viewer, it is always the same. Event 41, Kernel-Power The system has rebooted without cleanly shutting down first. This error could be caused if the system stopped responding, crashed, or lost power unexpectedly. Maybe I should also mention that, the computer does not seem to be overheating, at least from feeling the outside it doesn't seem like it. Hardware Diagnostics scan results in Passed for everything. I've dealt with it long enough, and now I'd like to get it resolved.

Thanks for the additional info, as I suspected the present PSU is underpowered.
A PSU calculator has just returned a recommendation of a minimum PSU output of 301W, that was allowing for an integrated video chip and one HDD, adding the HD6450 and a second HDD returns a recommendation of 330W, see http://images10.newe...tage-Calculator or http://www2.corsair.com/psufinder/ both are guides but tell you that the present PSU is insufficient.
A PSU that has a minimum 80% efficiency rating is advisable and always allow a headroom of 50 - 100W.

Thanks for the quick responses. I was under the impression that it was either the PSU or the graphics card overheating. But I see how adding on the second drive would definitely require more. Especially as I'm using my computer for a lot of multitrack recording (which is why i got the second drive). I'm not too keen on PSUs, but one of the results I got was the Enthusiast Series™ Modular TX650M. Would you recommend this?

Under normal circumstances I would have suggested that you try and borrow a known good PSU to try before purchasing a new one but as the present PSU is clearly underpowered there is no option but to replace it in any event.
I am not a fan of modular PSUs and would only suggest using one if a person was limited for space due to case size for example, the brand you linked to is very good and one that I recommend, one I suggest you consider http://www.newegg.co...N82E16817139020

Hopefully the present underpowered PSU has not caused any harm to other components but be aware that this is always a danger.

Before I do that, I looked back at the error logs and this all started happening January 11th, one or two days after I installed a PCIe firewire card. Could that have anything to do with it?
Also I didn't see this before but another error that shows up whenever this occurs is:

So its been a few days and have not had any problems at all. The last thing I did was disable my firewire card and since then everything has run smoothly. No errors, no shutdowns, nothing. Thanks again for all your help!
